通过AJAX将两个值传递给PHP文件

Question

right now I'm successfully passing one value to a Bootstrap modal via AJAX, however when I attempt to pass a second value my code stops working.

JavaScript

function claimOrder(str, stre){
if (str=="") {
document.getElementById("txtH").innerHTML="Blank Order ID";
return;
}
if (stre=="") {
document.getElementById("txtH").innerHTML="Blank User ID";
return;
}

if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("txtH").innerHTML=xmlhttp.responseText;
}
}xmlhttp.open('GET','assignuser.php?q='+str'&w='+stre,true);
 xmlhttp.send();
}

Button That Triggers Function

echo '<td><a data-toggle="modal" href="#mModal" onclick="claimOrder('.$order_id.', '.$activeuser.')" class="btn btn-success btn-lg">Claim</a></td></tr>';

Modal Called by Button

<div class="modal fade" id="mModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div id="txtH"><b>Loading...</b></div>
</div><!-- /.modal -->

PHP

<?php
$q = intval($_GET['q']);
$w = intval($_GET['w']);

etc... No changes were made to the PHP that worked before adding the second variable to the AJAX call except the extra line defining $w. If I remove the extra parameter from the function and function call line assignuser.php runs fine and the modal is populated, so I'm pretty sure the problem is somewhere in the JavaScript.

Answer 1

You forgot a + in this portion of the code:

xmlhttp.open('GET','assignuser.php?q='+str'&w='+stre,true);

So you will need to adjust it to:

xmlhttp.open('GET','assignuser.php?q='+str+'&w='+stre,true);
